5.3.4. Note relating to the type of paper
PRINTED ON ELEMENTAL CHLORINE-FREE BLEACHED PAPER (ECF)
PRINTED ON TOTALLY CHLORINE-FREE BLEACHED PAPER (TCF)
In the case of recycled paper, never use the words ‘chlorine-free bleached’ because it is impossible to certify the origin of all paper used in the recycling process (and therefore to guarantee that it is chlorine-free). However, the recycling process itself can be carried out without chlorine.
